Question:
Choose the equation that represents the graph below.

A. y = x - 3
B. y = -x + 3
C. y = -x - 3
D. y = x + 3​

Answer:

5(2x-8)+15=-15

10x-40+15=-15

10x-25=-15

    +25   +25 (add 25 to both sides)

____________

10x=10

divide by 10 on both sides

x=1

Answer:

x=1

Step-by-step explanation:

First youd distribute the 5 to the 2x-8 so that way you can combine like terms and make the equation smaller

10x - 40 + 15 = -15

combine the -40 and 15

10x - 25 = -15

add 25 to both sides to get 10x by itself on the one side. you have to add 25 to the -15 because the two sides must stay balanced

10x = 10

divide by 10 to get x by itself. you must divide since x is being multiplied by 10

x=1

Step-by-step explanation:

Elisa has 60 almonds and 70 pistachios and she wants to distribute them in bags so that they all have the same content and that there are no excess almonds and pistachios.

How many bags can you fill?

How many almonds and how many pistachios does she have to put in each bag?

=====================

Prime factors of the given numbers:

LCM(60, 70) = 2*5 = 10

The greatest number of the bags is 10

Each bag will contain:

Answer:

2x + 20 >_ 85

Step-by-step explanation:

In this equation, the 85 represents how much he needs to make. The greater than or equal to symbol is basically stating that he needs to make an amount greater than or equal to 85. Our variable, x, will tell us how many tickets he needs to sell, and the 2 represents how much each ticket sells for. 2x is just saying that each ticket sells for 2 dollars. The 20 is how much he makes on a daily basis without the ticket sales. We have to include that in the 85. That's where our equation comes from :)

Answer:

the height of the tree to the nearest tenth of a meter is 13.8 meters

Step-by-step explanation:

The computation of the height of the tree is shown below:

Given that

Distance from the tree is 10 meters

And, the angle of elevation of the tree is 54 degrees

Now here we used the trigonometry

[tex]tan \theta = \frac{Height}{distance} \\\\tan 54^{\circ} = \frac{height}{10}[/tex]

So, the height is

= 10 × 1.38

= 13.8 meters

hence, the height of the tree to the nearest tenth of a meter is 13.8 meters

Answer:

x=30/7

Step-by-step explanation:

you have to multiply both fractions by 5 to eliminate 5 from the first fraction(not the denominator of the second fraction) which makes the equation

x=30/7

Step-by-step explanation:

Isolate X first

[tex]\frac{x}{5} =\frac{6}{7}[/tex]

multiply both sides by 5 to get x on its own.

[tex]x =\frac{5*6}{7}[/tex]

simplify this fraction

[tex]x=\frac{30}{7}[/tex]

[tex]x = 4\frac{2}{7}[/tex]

Answer: A'Reana's weekly allowance is $100

Step-by-step explanation:

Backward Solution

To solve some problems, we can work backward, using the inverse operations, to arrive at the solution.

The problem explains a sequence of expenses A'Reana does with her weekly allowance. In the end, she had $37.50.

That final balance came when she last spent $7.50 on a pizza. Thus, before that, she had $37.50+$7.50=$45

This balance is half of her previously remaining money. The other half was spent on a new shirt. Thus she had 2*$45=$90.

Those $90 were left after she gave $10 to her friend Taylor, thus, the initial money was $90+$10 = $100

Answer: A'Reana's weekly allowance is $100

Step-by-step explanation:

7(3+4y)-15y=73

21 plus 28y-15y=73

21 plus 13y = 73

13y=51

y=4

Step-by-step explanation:

Step 1: Multiply the 7 into the bracket.(make sure that your signs are correct)

Step 2: Minus the 21 from the 73.( Because when you take a value over the equal sign the value's sign changes)

Step 3: Minus 15y from 28y.

Step 4: Divide 52 by 13( because when you take the 13 over it divides ,because on the other side lf the equal the 13 multiples with the y)

Answer:

y = -1/2 x + 1

Step-by-step explanation:

(-2, 2) and (4, -1)  are points of the linear function, that will be described as:

y = ax + b

setting x=-2, y=2:

2 = -2a + b, so b = 2 + 2a

setting x=4, y=-1:

-1 = 4a + b ⇒ -1 = 4a + 2 + 2a ⇒   -3 = 6a ⇒ a = -1/2, b = 1

y = -1/2 x + 1
